Start from a low level of net carbs to ensure you quickly enter ketosis (~ 20 grams of net carbs per day). When you detect ketosis after about 2-3 days, start adding net carbs (about 5 grams each week) until you detect a very low-level or no ketones (using Ketostix or blood ketone meter).
The fastest way to reach ketosis using your diet is by limiting carbs: 20 to 50 grams per day, or less than 10% of total daily calories.
